Resumo
The Trichoptera fauna in two first-order streams of Serra dos Pireneus. Goiás State, was studied from June/1993 to July/1994. The Trichoptera larvae abundances were lower in the rainy season in the two streams. The temporal distributions of the functional groups (feeding categories) was similar in both streams. The ordination by Detrended Correspondence Analysis (DCA) detected a higher temporal heterogeneity of the Trichoptera community in one of the sampling stations, probably associated with higher discharge variation. There is a large variation of abundance of some genera between the two studied streams.

ABSTRACT
The Trichoptera fauna in two first-order streams of Serra dos Pireneus. Goiás State, was studied from June/1993 to July/1994. The Trichoptera larvae abundances were lower in the rainy season in the two streams. The temporal distributions of the functional groups (feeding categories) was similar in both streams. The ordination by Detrended Correspondence Analysis (DCA) detected a higher temporal heterogeneity of the Trichoptera community in one of the sampling stations, probably associated with higher discharge variation. There is a large variation of abundance of some genera between the two studied streams.
Key words: Trichoptera, community, stream, feeding categories, detrended correspondence analysis
